Handle



May 30, 1950 H. M. LITTERIO HANDLE Filed March 29, 1948 IN VE N TORATTORNEY Patented May 30, 1950 UNITED STATES "rs-NT OFFICE 1 Claim.

This invention relates to improvements in handles, and more particularlyto the provision of a handle adapted to tightly hold files while in use.

The usual handle for files has a wedge shaped elongated hole whichbecomes enlarged with frequent use of the file and the file is nottightly held in place. On the other hand, when the file is tightly heldin place, it is difficult to remove the file to insert another file.

It is, therefore, an object of this invention to provide a handle whichwill tightly hold a file at all times when, the motions of the filewhile doing work tending to increase the grip of the handle on the file.

A further object is to provide a handle for files provided with means toenable a file to be easily and quickly removed when so desired.

A further object is to provide a handle for files which is made of twosimilar parts, easily assembled, and providing a good grip.

These and other objects are attained by the novel construction andarrangement of parts hereinafter described and illustrated by theaccompanying drawings, forming a part hereof, and in which:

Fig. 1 is a sectional view of a file handle embodying the invention.

Fig. 2 is a top view of the handle.

Referring to the drawings, the handle for files is shown to be made intwo similar sections, each of which has an internal flat surface I, andan outer rounded portion to form a hand grip. Since the sections areidentical, only one need be described.

Referring to Fig. 1, section surface I is shown to have a recess 2 inwhich are pivotally mounted by means of pivot pins 5 and 5, the levers 3and 4. Each lever has an upper inclined face i and a lower inclined face8, the portion of the lever carrying face I being shorter than theportion of the lever carrying the face 8, so that as the tapered end or"a file moves down in the recess it will engage the faces 8 to cause thelevers to rotate and move the faces I tightly against the upper portionsof the tapered part of the file.

The recess 2 communicates with an elongated recess 9 in which ispositioned a head It! adapted to rest on a shoulder l3 at the lower partof recess 9. Integral with and extending down from the head it] is a pinH which moves in a reduced extension of recess 9. The pin II isencircled by a coiled compression spring 12 which bears against ashoulder l4 and also bears against the head it normally tending to movethe head ill upward.

The two sections of the handle are secured together by means of rivets,bolts, or the like as denoted at it.

In operation, the tapered end of the file is forced down between theinclined heads or faces I and 8 of levers 3 and 4, until the grip of thefaces on the tapered end becomes so great that further downward movementis prevented. The inclined faces I are longer than the inclined faces 8so that when a file in the holder engages faces '5, the faces 8 arerotated into a position to tightly grip the tapered portion of the fileand also causing a tight grip by the faces I.

The spring [2 will urge the head ID upward until it engages the tip ofthe tapered portion of the file as shown in Fig. 1, the compression ofthe spring insuring firm engagement of the head and tip. When it isdesired to remove the file, it is only necessary to strike the pin IIwith a tool or against a hard surface, which will move the file upwardfrom engagement with the inclined faces I and 8. Obviously, the lengthof the pin and spring can be arranged to properly accommodate taperedfile ends of various lengths.

While the levers 3 and t have been shown to have square corners,obviously they may be rounded, the same leverage taking place regardlessof shapes of the levers.

The handle can be made of a light weight metal such as aluminum or itcan be made of wood, plastics, and similar materials commonly used forhandles.

The above description is to be considered as illustrative and notlimitative of the invention of which modifications can be made withoutdeparting from the spirit of the invention as set forth in the appendedclaim.

The invention having been described, what is claimed is:

A handle for holding files, comprising two sections of similar shape,each section having at its upper end a recess communicated with anelongated recess in the lower end, said elongated recess having areduced extension, a pair of op- 3 posed levers spaced from each otherand pivotally mounted in the upper recess, each lever having an inclinedupper face and an inclined lower face, said inclined lower faceprojecting further into the recess than the upper inclined face, ashoulder in the handle at the lower portion of the main part of theelongated recess, a head adapted to rest on the shoulder, a compressionspring engaging the head and normally tending to move the head towardsthe levers, a pin connected to the head and encircled by the spring,said pin passing through the extension to the elongated recess, and ashoulder upon which the lower end of the spring rests.
